" *scALn Application'filed November 18,1930. Serial No. 496,450. r i i This invention relates, to personal weighing scales andmore particularly to indicator tripping. mechanism adapted to be controlled by a coin deposited in a coin chute generallyprovided in suchscales. y a

An object of this invention is aftripping mechanism for scales of this character which is operable. to permit the scale indicating means to operate positively and only upon 30 the insertionof a coin in thejchute provided for such purposes. i 7 a a A still further object is a personal weigh 'ing scalehaving a positive operating tripping mechanism for permitting the indicator to read only. when a coin has been dropped in the chute generally provided in such scales;

Still further objects;will readily occur to those skilled in theart uponreference to the following description and thejaccompanying drawingsin which a I Fig. 1 shows parts of a personal weighing scale embodying the invention. v I i Fig. 2 is a, diagrammatic view of a modification. v

5 Referring to Fig. 1 which shows the parts inthe position they occupy when a person is standing upon the weighing platformand before a coin has been dropped in place,.it will be seen that the scale includes a weighing lever 10, shown diagrammatically as mounted upon a bearingor fulcrum 12, and having a load indicated thereon .at 14. One end of the lever is connected by a rigid arm 16.to a ,bi-metallic thermostatic element 18, which in turn is pivotally connected'tothe slotted end 20 of a rack rod portion22by means of a pivot pin. 24. The rack rodin eludes two portions, the lower portion 2 2.connected to the thermostat, and the upper portion 24 provided with a rack 26 adapted to engage the gear 28 connected to theindicating needle 30, these portions of the rack rod beingformed ofhollow tubes. Y

In the upper end of the portion 22 a bar 32 is disposed, this barcb eing secured to the porv tion 22 in any suitable manner, as by the rivets 34, and being of such a size that theupper portion 24 can slide thereon with practically no friction. The upper portion of the rack 9 rod isprovided with a. collar 38 secured there'- to by the set screw lO'and having. ajflange i adapted to be engaged bythehook 44 .forine d on the .end of the leg 46 of thecounterweight ed T-shaped tripping element 50, the latter be ng pivoted to the frame of the scale atthe po nt 52. 'One end'of the tripping element- 50 ls bent outwardly with respect to themajor portion thereof to provide an arm 541: which s disposed below theopening infthefcoin chute 56 so as to be engaged by a coin which slldes down the chute. fA stop 581 provided on a frame part60 is disposedbelow a por t1on of the tripping element 50 so as to limit the downward niovemen'tgof the latter; The end of thee'lement 50 may be provided with a counterweiglli 63 tokeep the arm 54'11'ear the bottomof the chute 56 and to keep hookf t t under collar42. I. The operation of the foregoing. parts will readily be observed. With the parts in their present condition,'that is tosay, with a per: son standing upon the Weighing platform and without a penny having been dropped 1n the slot 56, the lower portion of them-k rod is separated from theupper porltiong -t he lower portion having been'moved by the load on the weighing lever and the upper portion a i i being held stationary by the hookltlofthe tripping element5 When a'coin is dropped inf'the chutel56, 9 1t engagesthe arm 54:.o'1t'the tripping ele; ment, causing'the latter to move pivotallj,

on the pin 52 and to fmove the hook 44jout froin under. the. collar 42:. Thereupon the upper portion of the rack rod can dropas permitted by the lower portion and accord-H ingly will rotate the indicating needle 30 a distance to correspond to. the efl'ect ofthe load. When a per form, the springs'provided in suchscales and indicated diagrammatically at. 61-will pull the lower portion of therack rod up;

wardly until it meets the upper portion 24; y Then the springs will pull them bothupwardlyuntil the collar 42 passesabove the hook 4A so as to rest thereon." The hook,fit'mu'st V be remember'ed has assumed its position due to the fact that the coin has' drop'p'ed' out of son steps offthe wei hing piaithe coin chute 56 thru the slot 62 in the side 7 wall of the'latter.

In order to insure the operation of the scale in the event a coin is droppedin the slot betore the person steps on the weighingplatform, in'ea'n's inq luding an eleinent 64,;secur'd v to the rack red 24 loj 'the Set 66 is pro: ;-vided. The element 64 has a right angula-rly bent porti n 68 .i O l15 a iqlo l s theaslotg 62, inj-he coin chute 5 6 s 'tha-t a coin deposited in the coin'chute 56 cannot move out of the chute thru the slot 62 until the rack rod and the arm 68 have been lowered toiree the slot 62. This action will take place after the tripping element has beenswung on its ive'tthe oinzand after a road has been 7 praeea on the weighing lever 14;
